MICHIGAN SKYLIGHT CONSTRUCTION Application filed. June 6,

Ahiong the objects of the invention is a lens holder which is subject to proper and permanent anchorage in the plastic material with which they are generally'used and which shall be of economical and efficient construction.

Another object is a simple, safe, cheap and efficient lens holder which will effectively support the lens in its opening and will not be subject to some of the disadvantages now found in devices of this character.

,Still other objects will readily occur to those skilled in the art upon reference to the following description the accompanying drawings in which I Fig. 1 is a plan view of a skylight involving the use of the present lens holder.

Fig. 2 is a section taken on the line 22 .of Fig. 1. i M

.1 1g. 3 is a perspective view of a portion of the lens holder and made in accordance with the present invention.

Fig. at is a section through the lens holder showing an alternative location of the anchor portion.

In the drawings as indicated in Fig. 1, the skylight is shown as constructed of a concrete frame portion 10, which will include reinforcing members 11, and lenses of glass 12, which latter may be of the usual plate glass with or without wire reinforcement.

Fig. 2 shows a section through the frame work for supporting the glass 12, and shows that the glass is supported upon the lens framewhich latter consists, as indicated in Fig. 3. of an upright web 20 having a trough or gutter 21 formed integral therewith and extending inwardly of the frame. The sides or portions-2O ettend for a short distance erticallv down from the extreme upper edge and, at a point at or about the junction of the gutter 21 with the portion 20, it is curved outwardly as indicated at 22. The curve of the portion 22 is preferably on a comparatively long radius and will be preferably less than 90 degrees of the arc. The reason for this will appear from Fig. :2 which shows the lens 1929. Serial No. 368,903.

holder imbedded in the concreteframe Work 10. The portion 22 is preferably not bent sufficiently to interfere with the placing of the rods 11 but should be well away from ihe surface 25 of the concrete. It is proposed to extend the concrete up to the bottom portion of the trough or gutter 21,but not over the outside portion. This gives a substantial body of concrete beneath the gutter and one which has no thin edges to crack off and make unsightly places.

Instead of locating the anchor portion at the bottom of the trough it may project from the wall 20 intermediate the height thereof as indicated at 22a.

The glass will be mounted in the gutter 21 as indicated in Fig. 2 with suitable packing or calking material 26.

Now, having described the invention and the preferred forms of embodiment thereof,

it is to be understood that the said inventlon is to be limited, not to the specific details herein described and illustrated, but only by the scope of the claims which follow.

o claim 1. A frame for supporting the lens of glass sections of skylights or transparent pavement comprising a metal frame adapted to be embedded in concrete and showing in cross section a comparatively thin upright vertical L portion having at its lower part a thickened inwardly extending gutter member for supportingthe glass, and a downward extension curved outwardly from said vertical portion and forming an obtuse angle therewith, to serve as an anchor in the concrete material, said gutter member having a beveled portion, adapted to form a continuation of the surface of the concrete material.

2. A frame for supporting the lens of glass sections of skylights or transparent pavement comprising a metal frame adapted to be embedded in concrete and showing in cross section a comparatively thin upright vertical portion having at its lower part an inward- 1y extending gutter member for supporting the glass, and a downward extension curved outwardly from said vertical portlon and forming an angle therewith, to serve as an anchor in the concrete material, said gutter member having a beveled portion, adapted to form a continuation ofthe surface of the concrete material, and a horizontal portion, there being no concrete on one wall of the beveled portion.

3. A frame for supporting the lens of glass sections of skylights ortransparent pavement comprising a metal frame adapted to be embeddec in'concrete and showing in cross section a comparatively thin upright vertical portion having at its lower part an inwardly extending gutter member for supporting the glass, and a downward extension curved outwardly from said vertical portion and forming an angle therewith, to serve as an anchor in the concrete material, said gutter member having a beveled portion, adapted to form a continuation of the surface of the concrete material, and a horizontal portion, there being no concrete on one wall of the beveled portion, the intersection of the beveled portion and the horizontal portion being a relatively straight sharp edge.
